You must understand that the likes of Ottoman, Seljuk and Safavid sultanates were by no means impressive according to the Indo-Muslim standards.
Let me explain:
In 1527–28, the Ottoman Empire spanned a landmass of about 3 million km² and yielded a revenue and tribute of 537.9 million akçe (≈ £9.96 million).
At the same time, the Muzaffarid Sultanate (~350,000 km²), just one of the 7-8 major Indo-Muslim polities, yielded £6.79 million in crown revenue and £7.7 million in tribute, totalling £14.49 million.
By 1683, the Ottoman Empire had reached its territorial peak with a landmass of 5.2 million km², a population of 28 million, and a revenue & tribute of 12 million ducats (≈126 million livres).
At the same time, Indo-Muslim polities were spread over roughly 3.7 million km², but commanded a population of about 130 million. Remarkably, just 4 out of 20+ provincial divisions (Agra, Delhi, Gujarat, Bijapur) alone yielded a combined revenue of 152 million livres.
Let us go further back. Take the example of Malik Maqbul Tilangani, the wazir (prime minister) from 1351–1370, and effectively the sole supreme administrator of the Delhi Sultanate. He drew a salary of 13 lakh silver tankas (≈15.6 million Persian dirhams) per annum.
This was equivalent to about 87% of the annual revenue of Mesopotamia (~400,000 km²), which stood at roughly 3 million dinar-e rayidj (≈18 million Persian dirhams).
Moving forward, in 1806, the Iranian monarch Fath-Ali Shah Qajar ruled over a landmass of about 930,000 km² and drew a revenue of £1,527,702.
In 1791, Nawab Fateh Ali Khan Bahadur, just one among many Nawabs, governed a territory of about 250,000 km², with revenues amounting to £2,749,269.
Let us move further to the era of Riyasati Amal (princely states era). Iran’s revenue under Reza Shah was 246 million rials in 1925–26, rising to 3,160 million rials in 1940–41.
By comparison, the combined revenue of just four Indian Muslim princely states (Hyderabad, Bhopal, Junagadh, and Rampur) amounted to approximately 60,070 million rials in 1939–40.
In conclusion, Indo-Muslim polities not only generated significantly larger revenues, were incomparably lavish but also governed and dealt with a far greater population base.
At its peak, the Ottoman Empire administered roughly 21% (about 1/5th) of the population scale managed by Indo-Muslim polities. Given this comparison, one can reasonably infer the relatively smaller scale of entities like the Safavid Empire and the Seljuk Empire, which were considerably more limited in scope.
There is simply no meaningful comparison between any other Islamicate sphere and the Indo-Islamicate world in terms of scale, revenue, and demographic reach.
