The "soulless bowl" term is lazy at this point and seems to be thrown at anything at all that might be new. Yes the Emirates and to an extent Wembley fell into a 00's trend of uniform stands with a corporate middle section all around that meant a disconnect in atmosphere between regular fans in the lower and upper tiers. Those may correctly be described as soulless bowls but modern stadium architecture has moved on from that period
It's disingenuous to infer that Everton fans are complaining about lack of atmosphere. Yes there will always be a few who give out, thats natural as a significant amount of people simply hate change. However the feedback both from Everton fans and travelling fans for that stadium has been very positive in general, both in terms of atmosphere and experience. The trick is to provide significant pockets of regular match-going supporters in the same area, very steep concourses to be close to the pitch and be strategic about where you're placing the corporate sections.
Even the Spurs stadium, while being glossy and a bit London in nature, isn't soulless either. Its an impressive place and the atmosphere has been fine, with the single south stand wall being a cool feature that helps create noise. Some of their fans also hated change as is the norm. Same thing happened in Munich with their new ground in 2005 but now its generally regarded as one of europes best and despite its location out of the city, most love it
The best example worldwide of a new stadium that doesn't automatically become a "soulless bowl" is the Minnesota Vikings stadium built in 2016. The design of that is awesome, was immediately loved by fans, and because of the acoustics managed in the design and with the roof, they managed to make it the loudest ground in the NFL straight off the bat
