100 no but 90-95 is possible but hard to get. 70-80 is standard for consumer grade stuff

IME (Germany), cheap LED bulbs usually have CRI 80 and you can find a few(!) bulbs with CRI 95 in most shops. The are often of the fake filament type, which usually comes with other good properties such as looking nice and not flickering. But you have lower efficiency, not dimmable, few color temperature options, and medium brightness (~80W incandescent equivalent) at best.

There are some options that come pretty close: e.g. (no association) https://www.waveformlighting.com/absolute-series

How about trying MHL instead of LED? AFAIK 120 Lm/W is not a limit for an arc lamp and CRI 100 is possible.
