Yeah I own the old laserdisc release of Dr. No and it’s the standard version. I heard rumors old copies of From Russia With Love had “what a performance” at the end but that was debunked. So I don’t know how possible it is the beta is uncut, but I’m interested to see.
There’s an AMC airing of Goldfinger from the early-mid 2000s floating around the internet that has “James bond will be back in [on her majesty’s secret service]” at the end instead of Thunderball. So if that version of Goldfinger still exists, maybe the uncut Dr. No does
