This is correct, and for the exact same reason. LED TV's are backlit by white LEDs, that's the item that looses intensity over time due to phosphor degradation. Plasma TV's are 100% based on...

Generally speaking they tend to have a narrow beam like a spot light, they shimmer nicely like MH bulbs but you'd need perhaps 2-3 units to spread the light around enough... I don't feel they bother...
