I compared the momentary maximum output at the default ceiling. I used the same battery (at 3.90V). Both lights arrived with the same 50% FET firmware 0000-2024-04-20
At ceiling:
The modded TiCu w DD 4500k peaks at 315 lumens
The stock 4000K TS10 MAO peaks at 340 lumens.
The peak ceiling output of the DD4500K is 8% lower than the 4000K CSP
