I can make some fairly expensive suggestions which are high quality but you pay through the nose for the privilege.
These are, without a doubt, the highest quality Tungsten (warm) or Daylight (cool) bulbs you can get in terms of colour accuracy for domestic use in my experiencehttps://store.yujiintl.com/collections/ ... unit-2-pcs
Although they seem to be out of Daylight bulbs at the moment these are still demonstrably the highest quality colour accuracy E27 bulbs I've found for domestic use. Yes, I've used Philips, Cree, Osram, etc. Doesn't come close, although these are slightly less efficient. The Tungsten ones are really fantastic, it's obvious next to another bulb with a Macbeth chart. Yuji are legit, they're a phosphor company and their products end up (I suspect) in a lot of commercial film heads.
If they're not what you're looking for exactly, try these for expensivehttps://www.quasarscience.com/products/ ... 7389686842
I haven't used these specifically but I have played with one of the other fixtures the company makes. Again, I expect these will be of superior colour quality based on the 4 foot fixture I played with but I haven't used these e27 units specifically. The company is legit, makes film fixtures (which are pretty sweet) and have good metrics on their other daylight and tungsten units.
I don't think either of those are dimmable if that's important to you.

I have half a dozen of these, no the colour accuracy isn't great (not bad, just not great) but they are fun and I like the light scheduler. The daylight end of the bulb are probably better than the warm side but I think they're about as accurate as a Philips. Yeah, RGB smart lights are kind of silly but I like playing with them.
None of these are cheap but you get what you pay for. Really, the standard is now much higher than it was 5 years ago. There are some other, more bespoke, bulb companies that make high TLCI bulbs but these (all three above) are the best I've come across that you can order simply online.
