Niner RKT is Bloated

I've been looking for a new carbon FS bike, and something I'd expect in a carbon bike is it will be lighter than my alloy FS. First issue is bike mfg. seem to have a great aversion to listing weights for their products. Some do and sometimes they are way under (claimed weight vs actual). I've found that while looking at bikes any bike shop is more than willing to toss a bike on the scale when I ask.  I had my current Jet 9 weighed and it comes in just under 27 lbs. I'm considering a Niner RKT, yet Niner does not list any weights. I had the shop weigh the Large and it came out at 26.7lbs!!! I couldn't believe it. This is a full carbon frame, hi-mod carbon, at around 4.5 lbs (claimed). I think and my alloy frame is at least 6.5lbs. This particular Niner RKT was built with some questionable components (not a standard Niner star build), so I started to lookup weights to see what I could lose with by moving a few parts from my current bike:

• This bike has test pedals, so I'm going with a cheap wellgo weight of 348g (candy is 304g, so not much difference there 

• It has 2.4 EXO/TR Ardents, which are 800g vs my 2.2 ikons at 640g, so significant savings of 320g

• It has a stealth reverb dropper, so losing that will save about 250g 

• I thought it was setup with tubes which would add about a pound but it's not according to the shop.

• It has alloy bars 300g. My carbon easton's are listed at 188g, so will save about 110g there

• But it is setup as a 1x and I want 2x, so I'll add about 300g for extra chainring, shifter and front d.

So, taking all this into account I come up with about about a 430g savings (1 lb) savings, when I make a few changes. The bike would be still rather hefty for an XC machine at about 25.6 lbs. This is really disappointing for a $5K bike, compared to my ride. I know there are advantages other than weight (carbon stiffness, remote rear lockout, stiffer wheels), but I expected to be at least in the 24lb range. I imagine the Boost components are adding weight, also I'd be going from Crest to Arch wheels (about 160g difference), but I still can't make sense of this. If the bike does in fact have tubes in it then that would at least get it to 24.5 lbs and make a lot more sense, but sales tech swore they were stans valves.

BTW, another bike shop that had a Niner RKT in a proper 3-star build (with niner carbon cockpit) weighed in at 26.1 lbs, and they swore it had tubes, so that would be just about 25 lbs even, tubeless, no pedals, still a bit chunky.
