That is beautiful both ways!!

I’m currently making a coffee table from a red oak slab. I needed some oak for the legs. In my own collection of wood, I found some pieces that I had marked as “oak”. Once I started cutting and planing it, I was very surprised at how green/yellow it was. It also feels denser and heavier than oak. I started to consider whether it was black locust. I got this wood from a homeowner who was cutting down a few trees: an oak, a maple, and a black locust. I also got some small pieces of black locust from him, so there could have been some confusion while collecting and labeling these pieces. I still haven’t done the black light test yet – but I will.

I have just checked several samples of recently cut red oak. None glow.

Clear finish will not change the glow. But keep in mind that slow surface oxidation will cause it to diminish over time. Maybe six months to a year. The finish will slow it some.

Yes, facegrain basically confirms my initial guess. I maintain that it’s most likely bloodwood (not cocobolo) and jatoba.
