Man, thank you! I'm loving your suggestion of ditching the CST for the ACES transform and, yes, much better result! Now, since I'm working in sRGB, would you mind taking a look at my conversion with the following screen shots and confirming it's the right setting? 
	 
	There is still a WB shift (no LUT applied), but I understand that's due to the white points as you mention. 
	 
	Also thank you for pointing me to the new LUTs! I should check them out! 
	 
	Appreciate you 🙏🏼
