Probably not, but it’ll be nice know the bin values. With a dedome, tint shift is often inconsistent and the impact on lumens is unknown. This removes all of the darkness and unknowns of doing a dedome. It’ll also save the grief of ruining emitters with a failed dedome.
XLamp XP-L High Intensity
Industry’s First High-Intensity LED
The XLamp® XP-L High-Intensity LED is the first of Cree’s new class of High-Intensity LEDs optimized to deliver maximum candela through secondary optics. The XP-L High-Intensity LED is the first single-die LED to deliver over 100,000 cd in a 4-degree beam with a 50-mm diameter optic at 10 W. Built on Cree’s breakthrough SC5 Technology™ Platform, the XP-L High-Intensity LED delivers more than double the candelas of the industry’s previous highest-performing single-die XP-L LED through the same optic. The new high-intensity LED offers a drop-in ready upgrade for XP-based luminaire designs, enabling manufacturers to achieve higher luminous intensity with minimal redesign to accelerate time to market.

It looks like there is a just a thin layer of silicone, likely to protect the phosphor and bond wires. This might mean surface brightness will be some percentage lower than a typical dedome, but reliability and tint should be better.
