Well, I won't claim expertise but I have a lot of NRI friends and have been to India. 'Loving' White people is not a universal thing in neither India nor the rest of Asia. A lot of these stories is people hyping up their good experiences and not telling (or being too culturally aloof) to know when they aren't welcome.
In India you can say there are a group of people, typically aspirational and with some education, who got their views of White people primarily from TV and movies. They learned about Brad Pitt, not the dudes that engineered the Kolkata famine. They may see the West as culturally aspirational and though they aren't the majority, there are enough of them to feed the perceptions of foreigners that they are 'the shyt'.
For upper class, highly educated, and rich Indians, most in my experience will be damned to take 2nd place to any foreigner, especially a White one. Those who know their history don't have a romantic ideal, especially of the British, either. This includes big business people, academics, and probably most Indian politicians--Congress or BJP. Remember India made a point to have a self-sufficient domestic industry including nukes, nuke subs, and other shyt. They opposed America for most of the Cold War and were more closely aligned with the Soviets. Not exactly White worship.
The light skinned being better phenomena is something I cosign but that isn't necessarily the caste system--every friggin country in Asia and the ME is on that shyt
Poor Indians will praise anyone with bread just like
@GetInTheTruck said.
That being said, I think there is a harder edge and possibly more arrogance between Africans and Indians now India is more developed and pulled away from Africa in growth. Back when we were all poor, there was still shyt (like in S. Africa) between Blacks and Indians, but people also forget how Nehru supported African independence and Indian UN troops kicked the shyt out of the White man favorite, Moise Tshombe, and his secessionist Katanga in the Congo.
Now NRIs can be a mixed bag towards Whites. The 1st generation is cordial but aren't trying to marry White people or see their kids do so. They may act deferential but usually with other goals in mind (i.e. business advancement). The kids, depending on where they grow up are schooled and are influenced by, range from 'good sons/daughters', to rebels, to assimilated/pseudo-White. Also, despite the Coli propaganda, there are a good number who date or now days even marry brehs (though family flak and religion is still a huge issue), a good number approached me in my prime
