Not sure about Investment into 4K :/

[Reflection]

I recently got back into physical media with buying cheap blu rays, i own dvds but moved away from it with streaming. But i am back on board and have been enjoying listening to the commentary tracks on the Star Wars Blu Rays.

I've been eyeing the Panasonic DP-UB450EB-K 4K player which you can get for a reasonable price, but the cost of the actual 4K discs is putting me off, i can get some movies for £1 for a used Blu Ray and that same movie in 4k costs £20, for slightly better image quality and HDR the jump in price doesn't seem worth it, and i've seen HDR on my TV with games and movies on my TV, i know how good HDR can look, but i can't really afford to buy a lot of 4k movies, i would really only buy starting off Blade Runner, Apocalypse Now, and Akira maybe.

Do you guys see 4K Blu Ray discs coming down in price any time soon? ... also i already own 1 4K blu ray (that i can't watch) The Hitcher because i got the box set.

Also how would you rate the difference between 4K and regular 1080p Blu Rays .
