i'd send the blu rays back and go digital. 1. dont need to buy a new blu ray player. 2. digital movies are cheaper than discs...even 4K HDR ones.
OR just play the discs on your console. i dont know about the C2 but my CX has "HDR Effect" which converts SDR into HDR. its not proper HDR of course but it does a decent job. I dont have any consoles so i sometimes use my old standard bluray player to watch movies and i use the HDR effect setting for them. even if the consoles dont support Dolby Vision surely they must support another HDR standard? i dont know any difference between HDR10, HLG, or DV. its all the same to me.
i dont buy discs anymore. i did think about moving to 4K HDR but again i dont have a console and i didnt want to buy a dedicated player and replace my discs. so i just buy movies through Apple or Amazon. recently i bought the LOTR and HP box sets. the HP one was £35 for 4K HDR but to buy the discs it is like £60+
you could do that and wait and see if new console revisions support dolby vision. there are rumors of a PS5 Slim this year. then you can sell a console and buy the new one and you wont have consoles AND a dedicated player
Please, don't do what this person does. HDR effect is simply a bastardization of the original picture - like soap opera motion interpolation, you should never do that.
All non HDR Blu rays are encoded in SDR 8-bit standard and cannot be simply upconverted to HDR - the information is simply not there. What you end up is simply blown out highlights, crushed shadows to achieve "HDR-like" effect but it's all fake. The colors are screwed up as well. Don't get used to colorful crap, it's not worth it, especially as you have a nice Oled.
Digital codes are fine but still much more compressed than a full 4k Blu ray would be. Hell, even standard Blu ray is often encoded with a better codec and a higher bitrate than a digital file or God forbid - Netflix stream. This compression is especially true for audio.
I got a Panasonic UB824 in addition to my PS5 and it's worth it imo. If you want to get the most out of your movies I suggest, in order of importance:
0. Go online and read up on TV picture settings and modes. Read up on SDR, HDR, encoding and compression. It's free and a lot of people get it wrong. (See above) Make sure you even want to dig deeper.
1. Calibrate your TV and disable all unnecessary motion/interpolation/color effects. Calibrate for day, night SDR, HDR and DV modes.
2. Invest in sound - 5.1/7.1 + sub. Dolby Atmos support. Headphones are nice but nothing beats a real stereo system.
Now you may start noticing the difference between streaming/digital and physical disk quality.
3. Invest in favorite disks - test of you even want to collect physical
4. Invest in player. Sony is a good budget solution but if you have extra cash - Panasonic is just better and you don't have to manually enable Dolby vision every time.
