You're looking for a very high level feature which isn't published in documents intended for consumer viewing. Your best bet would be to acquire some developer documentation for the device.
It probably wouldn't make a difference how they implement time synchronization as long as they do it well. The least predictable factor in the system is the wireless connection between your device and your router. Latencies will vary far more in a WiFi connection than an internal clock that the devices use.
It looks like you don't need a Sony device to use Remote Play...

I found this quote from a some guy on another forum that may help clear up the issue, he says all computers are good to go:

Although, the guy got banned from those forums, so idk if I would believe it or not.
That was good, I must say
Doing that here would make it less fun to log in. It's like opening birthday presents from someone you never met who lives in Japan and likes to shop their vending machines..
IKR - totally agree with you there. These posts are 90% of the reason I hang out here. Nothing at all wrong with them, or him.
To actually answer your question:
Invariant TSC is a CPU timer. The OS can use it for timing things. If you were using a software-based display driver, it could be used for clock timings.
But most video output devices have their own hardware timer for display output timing, as part of their output interface package (the video card's physical outputs). The display driver will then use that hardware-level timer for driving the display, the CPU timers aren't used at all.
So... the phone will have it's own built-in display driver as part of the Snapdragon/Adreno SOI package. Sony will have their own controller to drive whatever display they put in that. It drives at the display native resolution 1080, progressive scan (most PC/PC-based devices are progressive because it's better and they can). The PS4 has a hardware output driver that runs the output of their GPU to the HDMI port on the back.
The only reason you would use interlacing would be for bandwidth concerns. LCDs can't even really display interlaced signals natively, it originated with the CRT electron gun scan pattern across the phosphor screen. The bandwidth-saving is why it's so popular in Cable/Satellite distribution - You can get 2 HD channel if they are interlaced over the same amount of bandwidth as a single progressive scan channel, so you can pack more channels on your service.
For live streaming over the internet: that deals mostly with higher levels of compression, resolution capping, and capping frame rates. PCs very, very rarely use interleaving anymore.
Just to comment on your original OP.
The Playstation App only supports "Second Screen".
Playstation 4 "Remote Play" is reserved strictly for the PS Vita handheld console.
And Sony's new phones - DrBaltazar appears to be correct about that:

Interesting.
I own a PS4 and just not sure why I would play it on my phone instead of on my TV if you have to be on the same wifi network.
The wife is watching her favorite show in the den, kids have taken over the spare TV. I can see where streaming PS4 games on a Vita or through your Sony phone can come in handy.

Yeah, I play more games on the WiiU using just the handheld than I do actually turning on the TV. It's pretty handy, especially if I'm just trying to kill 15-20 minutes while the kid gets ready for bed (and I don't want him staring at my game rather than brushing his teeth).
