Dasnac Westminster Noida: ₹12 Cr investment potential?

Came across this video about Dasnac Westminster in Noida, Sector 146. Looks pretty lavish, ₹12 Cr for a 4BHK! The video showed massive balconies and the 146 Metro connectivity seems good. It's low-density, only 132 homes. I'm wondering about the investment angle here. With such a high price point, will it really appreciate well in the long run? Ya fir, is the rental yield bhi decent for this segment? What do you guys think, is ₹12 Cr a sensible investment for future returns in Noida for this kind of property?
