Non-HDR commercial panel + 5.1.0 Denon setup

I‘m a rookie here, this is my first home theater setup. I pasted my specs below. In short, I bought a commercial TV with no HDR but am beginning to wonder how much I am missing out on HDR. I don’t stream all that much aside from news and stuff, mostly only watch discs. I watch way more older (90s and before) films than current ones, though I do watch more recent TV shows if they get a disc release.

I A/B’d Point Break on 4K UHD vs standard Blu-ray on my panel. They looked very close; maybe a slight sharpness edge to the 4K, nothing dramatic. On audio, since I’m 5.1.0 with no height, I have no need for the Atmos tracks.

My question is, given the non-HDR panel specifically, am I underrating what the 4K discs give me even without HDR? Would it be worth getting a panel that can support HDR?

Similarly: if I have a 4K and Blu Ray disc, is there any reason to watch one over the other? Is there any meaningful sound or video upgrade I would get on a 4K disc over a Blu Ray?

Any other suggestions for settings? Overall I am super happy with this set up, just thinking things through.

Thank you for any help you can provide!

- Display: LG 65UM340E — 65” commercial/signage panel (IPS, ~250 nits, no HDR of any kind).

Revisiting my old friend on vinyl

just got my LTMR vinyl reissue. hard to describe how much this album means to me. sitting here listening to the songs, every single one I know deep in the depths of my soul but given a new vibrancy on wax. reading the lyrics and liner notes that STILL have so much relevance, urgency and feeling. what a band, what an album. thank you Propagandhi for squeegeeing my third eye (to quote the late Bill Hicks) and waking me up from my stupor all those many years ago.
