jommy This is what we are trying to say to everyone, you have to see it with your own eyes to believe. Everything, and I mean EVERYTHING is higher in quality when using the PCVR Steam DeoVR vs. Standalone Quest 3 DeoVR. The interface, the Cams and the videos.
As for the live cams, I humbly suggest to check "Mandi4pole" she's not only amazing and deserve support, but she's using 6K VR Cam with perfect angle and scale and super clean lenses. She's really taking this seriously and professionally, you can see the difference in quality very clearly when you go back and forth between the two Platforms/ Apps with her Room.
As for the actual videos, I suggest to download the Original/ High bitrate of SLR's Originals recent 8K videos, and again, you can see the difference in quality in favor of PCVR DeoVR when you go back and forth, but remember, you have to copy that video from the PC to your headset's local storage and play it from there so you can have a fair comparison, this is what I did with my Quest 3. and I believe you'll see the difference even better than me, because Pico 4 is BETTER than Q3 for PCVR (2064x2208 pixels per eye with garbage tilted screens vs. 2160 x 2160 pixels per eye and standard, straight screens).
PS: Why I said garbage tilted screens? Because they cause aliasing issues when gaming and especially when reading texts. Why Meta did this garbage? Just to increase their headset's FOV on the specs paper. Not worth all the troubles they caused by this move at all.
Respectfully and Best Regards.
