Do you have a 4k TV? If not - no reason to upgrade to 4k player.
I have observed that upscaling to 4k can create some strange looking images. The upscaling and also enhancement to HDR makes the images look un-natural - like they were shot in a studio with very bright lights (perhaps they were....).
Real 4k Blurays look astounding so that's why you should buy the latest technology - stop living in the past.
Sound quality on the UDP-205 is better than the 105 - particularly on voices, which would be a consideration for Opera.
