Super luxury amenities are often just marketing fluff

Visited Altura Greater Kailash 2 Super Luxury Floors last weekend. The brochure looks amazing, but I'm genuinely worried about the actual usability of those fancy clubhouses. Currently in a 2BHK, thinking of upgrading to a 3BHK there. Is the price jump worth it for amenities that might just be ghost facilities, rarely used after a year? Also, what's the parking allocation situation like? I already have a home loan, so every detail matters. Is it reserved, or a daily fight for space? Any real-life experiences?
