Also old information. The high CRI CFLs tubes (intended for use in the graphics industry) I have from Philips (TLD Master 950) are on par with the efficiency of LED lamps.
I'm not comparing them to LEDs, I'm comparing them to more common 80+ CRI fluorescent lamps. Here's the data straight from Philips:
First the TLD Master 950 you mention, looking at the common (in the US) F32T8 size which is a 4' long 1" diameter tube:

Luminous Flux (Nom) 2330 lm
Luminous Efficacy (rated) (Nom) 65 lm/W
Next the TLD super 80 which is a trichromatic lamp with a CRI of 80+:

Luminous Efficacy (rated) (Nom) 93 lm/W
So from that we have >80 CRI lamp is 93 lm/W vs >90 CRI lamp 65 lm/W. I said previously that the 90+ CRI lamps have a penalty, achieving around 60-70% of the efficiency of lower CRI lamps, which matches the information above, both F32T8 which are nominally 36W, looking closer I believe these are a European product, in the US F32T8 lamps are 32W. All this is straight from the horse's mouth so to speak.
I don't have the data on hand but IIRC the efficiency penalty between low and high CRI lamps of the older halophosphate type was similar, the newer rare earth trichromatic phosphors offering a significant boost in efficiency but to get the 90+ CRI you still need to add a true red phosphor and in doing so you sacrifice efficiency. In many cases this is a worthwhile trade, but my point still stands that there is no free lunch. The reason 80+ CRI lamps are so common is that they are generally considered the best compromise between cost, efficiency and light quality. For applications where color rendering is less important, there are 70+ CRI lamps which are cheaper and even more efficient. For applications where color rendering is more important, there are 90+ CRI lamps but they cost quite a bit more and as demonstrated above, come with a significant penalty in lumens per Watt.
Now I don't have data in front of me for a lot of LED lamps but I do recall some of the more recent A19 size LED bulbs I got having a claimed efficiency of right around 100lm/W with a >80 CRI however I have not looked at the current state of >90 CRI LEDs so I can't say whether they suffer a similar reduction in efficiency or just cost more. Trying to compare efficiency between bulbs and tubular lamps is also complicated by the often significant difference between lamp efficiency and system efficiency. There is a great deal of variation in how much of the light coming out of the lamp ends up getting to where you want it.
