It's kind of sad how down you are on your own preservation at times. If you want a realistic yet hopeful idea of how good a print preservation can look, check out Criterion's Blu Ray of Solaris. The production credits don't specify if it was scanned at 2K or 4K but it looks excellent regardless.
Even if your work or Mike's work technically isn't on the same level as the original negative, keep in mind none of us really know how well the original negative looks, what with the official Blu Rays being 720p for all intents and purposes, DNRed, and kind of lifeless. You could very well have an amazing preservation when all is said and done--and with those pesky cue marks gotten rid of. ;)
