I haven’t looked at that Philips bulb before. The listed specs are sparse. Link to Philips product page.
They do not say if the bulbs are rated for enclosed fixtures or recessed fixtures. Where did you see this claim? (edit: I see now, on the energystar.gov page)
Unfortunately Philips provides no photometric reports, no details regarding the flicker characteristics. One might be able to procure these from Philips.
The feature where the CCT lowers as it dims is nice, although a reviewer mentioned: “at about 90% dimmed, they seem to lose most of the amber color and go back to a soft white.” The dimming behavior might be dependent on the dimmer controls used. Ideally the bulb would be 3000k at the top end instead of 2700k, and ~1900k at the bottom or whatever can be realistically achieved.
