My biggest issue is that most of the tints int he latest nichia products are above the BBL and it drives me up the wall. The 219B still has some tints from below the BBL that are so much nicer to look at.

There is a solution to that if you can accept a loss in light level of 13-14%. I often use a circular piece of this filter (behind the lens) to correct a tint 0.004-0.005 (yc) down across the BBL curve.
Specs is here.
Can be bought here and many other places

Interesting product. Is the product you linked the specific option you recommend? I see there are other options on the page.

My application is home lighting. Specifically in dining and kitchen areas. I bought some of the 219c 4000/4500k cri90s thinking they were going to look like the 219b 9080 4500k. But as has been said there is a bit too much yellow for me. Could this film help my cause? And would the item linked be best or would one of the others listed with it better suit my application?

After my first experience with these filters from a sample booklet I made a report, see here.
I am fortunate to have a Color Analyzer so I can measure the color points (xc,yc) before and after correction. That is useful, being a tint snob.
My first aim was to correct the awfully green Xiaomi lamps to have a tint on the BBL locus (arrow d in the drawing). This is about 20/1000 or 0.020 on the yc axis (In the drawing I interchanged yc and xc axis, sorry).
An offset on yc of 0.005 is easy to see as a green tint so here we have 4 times as much.
The best job would be done by a 279 plus a 003 filter but that would cost 35% in efficiency so I decided for only one layers of filter 279, that worked fine.
My final choice was to buy three filters:

- nr.279 (minus 1/8 green). Used it a lot to remove moderate greenish tint. Also makes the CCT a little warmer. Also to correct the slight greenish 219C (in my opinion) towards the magenta side.

- nr.278 (plus 1/8 green). Aimed to correct LEDs that is too magenta. Used only a few times.

• nr.206 (straw color). To correct those awfully bluish (old) LEDs. Used it on many of my old lights with great result

I would advice you to ask for a (free) sample booklet from a vendor as I did. Then you can see the effect of a filter by shining a flashligt through the sample sheet (they are small, appr. 1.5 x 4 inch). Then decide which to buy. My local vendor did not have the half sheet size (cheapest) so I had to select carefully to save money.
