I have never used a Prism+ TV, but I once talked to one of the staff at Prism+ Sunway Pyramid. I was asking him about the TV capabilities, like VRR, HDR etc. He couldn't answer some of the questions directly, but he said I can bring my console or PC to test it at the shop. So that I can test out and see for myself. You could try bringing your PS5 to the shop and test it yourself.
