The reason why Luo Binghe (specifically Bingmei) is not treated on the same level as Shen Jiu by story is because he took on the difficulty of making his loved one understand him, this is between xin mo manipulating his trauma and obsession. He inherently, did not want to treat Shen Qingqiu cruelly at any time and was terrified of that outcome. Shen Jiu at no point cared if he treated Yue Qingyuan cruelly because he was convinced of his own narrative (in a similar vein to Shen Yuan thinking that Bingmei is still the same as Bingge).
And the what if doesn't work for Shen Jiu finding out about Yue Qingyuan's hardships because he is very jealous of others of his same circumstances being able to persevere and be talented. He did not want to be seen as an equal but wanted the entitlement of prestige and the cruelty that can be used from it, just as Bingge achieved during PIDW. It did not matter how much they were beloved, because they wanted entitlement while ridiculing love. Something that Shen Jiu instilled into his Luo Binghe. Because Shen Qingqiu changed that trajectory for Bingmei he was still able to believe in small kindnesses by one person not ridiculing that concept.
Shen Jiu did not care if he was actually loved. He used being unloved as his weapon to be worse because doing the opposite was much more difficult.
