Best LEDs for Convoy M21B & M21E

Guten Tag!

I have bought the M21B with the B35AM 6500K and the M21E with the GT FC40 5000K
Both unfortunately produce yellow centered donuts.

Do you know what LEDs are producing a nice spot in these hosts?
I like flood way more than throw and I like High CRI with ~5500K.

How about the FC40 in the M21B and an XHP70.3Hi in the M21E?

Thank you!
