Hello good day to you. Quick question

I have a blu ray player and the 2010 Criterion blu-ray release of Fellini's 8 1/2

Recently Criterion released an updated version of the film with new 4K digital restoration, and with blu-ray still available.

Is there a significant difference, or any at all, between my 2010 blu-ray disc and the blu-ray release of the new 4K restoration, when played on my blu-ray player?

Would it be worth it to upgrade my blu-ray to the new blu-ray or would I just be buying the same disc? I'm not interested at this time in upgrading to a 4K disc player.

Apologies if this has been asked before - it was too specific for me to run through Google and I didn't know how to ask it succinctly in a search bar. I had to wait 7 days to post the question on this sub because I didn't know how else to find the answer.

Thanks have a nice day.
