Those are concerns, but relatively minor compared to contrast, resolution, HDR, WCG, which laser does nothing to solve in this case (although it could, which is the real disappointment).
Consider this: I'm on my second bulb on my w1070 from 2011, and I watched around 5500 hours on the first one and 5000 hours on the second so far, and the replacement bulb cost me literally 80 bucks. Reduced brightness is indeed more an issue, but "laser" in and of itself is useful for image quality only if you exploit its ability to use wider colour gamut and/or attenuate the colours independently or faster (for pseudo "SmartEco" or dynamic mode).
Also consider that there are 3000-4000 dollar HDR projectors coming out this year, the new Optoma and JVC models, which are lamp based and many don't come with WCG despite having HDR. IMO laser lighting is a much better fit for higher priced HDR+WCG. Hence, I think the pairing of this model with laser to ignore the fact that a) it's still 1080p, b) still low contrast DLP, c) still WCG despite an ability to support DCI easily if they wanted to (maybe the lasers at those primaries would be slightly less common thus more expensive, who knows).
So yeah, I consider the fact that this has "lasers" to be secondary to its other characteristics which are probably the same as my 5 year old w1070. The current lamp based 1080p BenQs are quite quiet too, apparently, although yes all other things beyind equal it would be nice to have 20k hours and no brightness degradation and instant-on / off ability.
Maybe "gimmick" is too strong a word. Distraction, yes. It's a BIG SHINY new feature that delivers what an 3 80 dollar bulbs cost (in terms of lifespan). So maybe worth 240 bucks? More if you consider the even brightness. Instant on/off is "nice" but also hardly a big deal either.
I say all this as a huge fan of laser illumination (and LED to a lesser extent). I applaud LG for going the extra mile here but 1080p DLP without 3D is just a slap in the face and I'm not giving them my money. It's literally a firmware issue in all likelihood. Probably the feature even exists they just disabled it in the menu. Seriously, 3D is probably baked into the HDMI and supporting electronics for all these consumer 1080p DLPs and they went out of their way to disable 3D.
