There is indeed such a LED with the name 707MD.
707RD 707MD (thanks @koef3 for the correction) was reviewed here on BLF LED test / review - Hopthink TC7070 (neutral white high CRI) - round die LED with four chips .
BTW in Firefly parlance, supposedly (not confirmed) the R stands for rosy, and the M indicates “mildly rosy.” There we go. Crucial info that tint-snobs memorize LOL.
